8. Complete the PNNI tab fields, as described in Table 21-7.
Table 21-7. Add Logical Port: PNNI Tab Fields
Field Action/Description
Administrative
Weight table
Determines the administrative weight configuration for this PNNI
logical port.
• CBR, VBR RT, VBR NRT, ABR, UBR – In the Weight field for
each QoS category, enter the administrative weight to assign for
the network interface associated with the logical port. Enter a
value between one and 16,777,215, or accept the default value
(5040).
• Aggregation Token – Enter a value in this 4-byte field to identify
a PNNI outside link that interconnects two separate peer groups.
The default value is zero (0).
The aggregation token determines how this link is aggregated at
the next higher level in the hierarchy. Outside links connecting
the same two peer groups are aggregated if they have the same
aggregation token or if one link has an aggregation token value of
zero (0). If the aggregation tokens of different outside links are
not equal, and nonzero, each will be advertised in a separate
horizontal link PTSE by the associated parent LGN nodes.
Note: The aggregation token value is important only for outside
links where the neighboring nodes belong in different peer
groups.
Override Default
(for Forward)
Select the check box to specify the forward traffic descriptor (TD)
for PNNI routing control channels (RCCs).
Forward: To configure the forward TD for PNNI RCCs, select the button to the
right of the field. Then choose a TD from the Select Traffic
Descriptor dialog box. (The Override Default check box above the
Forward field must first be selected.)
The RCC is a virtual channel connection (VCC) used between
neighboring LGNs for the exchange of PNNI routing protocol
messages. It is used only in a hierarchical PNNI network.
Override Default
(for Reverse)
Select the check box to specify the reverse TD for PNNI RCCs.
Reverse: To configure the reverse TD for PNNI RCCs, select the button to the
right of the field. Then choose a TD from the Select Traffic
Descriptor dialog box. (The Override Default check box above the
Reverse field must first be selected.)
The RCC is a VCC used between neighboring LGNs for the
exchange of PNNI routing protocol messages. It is used only in a
hierarchical PNNI network.
